Last week, the attorney general and the director of national intelligencesaid they would let the companies reveal some things but not, regrettably, nearly enough. Companies can now give the public a better idea of how often federal agencies request information from them. But they can’t reveal what kinds of information, and how much, they dredge up. The government devised the new rules to settle a lawsuit from technology companies like Google and Facebook. They also amount to another missed opportunity by the Obama administration to fix the legally dubious way in which the government gathers intelligence.
